1.4-SVN [NOTstripped][validity: 1.00][frames: 2][xine]

[Andrew Turner]

Having just looked at my/Jeff's changes to DeviceManager, I start to
wonder if they were right. It seems from looking that after having
called getDevice, the pointer is always deleted. This is not what I
thought happened, and will be what's causing the crash.

I'm going out soon, but will fix this tomorrow if nobody else has -
maybe the easiest way is to just revert most of the changes to
devicemanager.cpp, given we are so close to a release... otherwise,
the thing to do would be to remove almost all the delete calls (and
maybe create a removeDevice method that deletes a device and removes
it from the mediumMap, for the cases where devices are truly being
removed).
